Hi all,
Just thought I would share a little checking up I did on the Alioscope
patent.  Only one patent by Alio is in the US PTO database:

United States Patent

                                                Abstract
An apparatus for the production of relief (three-dimensional) images
includes a single objection lens and a lenticular grating with a series of
cylindrical elementary lenses. An imaging surface is located behind the
lenticular grating. Each lens in the grating causes the image focused
thereupon to be reversed in relation to the axis of the cylinder. Electronic
means are provided to reverse the image focused by each cylindrical lens. 
                                     10 Claims, 13 Drawing Figures 

Anybody considering licensing the technology should review this patent and
the prior art, which is substantial.

Chuck
